One hundred and thirty five samples of certain manufactured infant foods were collected form five Governorates of Cairo, Giza. Alexandria, Monofia and Fayiom. Samples were examined for the natural occurrence of moulds and aflatoxins to determine their hygienic conditions. Some isolated strains of different types of moulds were examined for their ability to produce mycotoxins. Eighty four percent of examined samples contained different types of moulds such as Aspergfifus sydwfi, A. niger. A. fi'a vus, A. furmigaius, A. versicoior; A. candidus ,Fusan'um rosum, F. compartum, F. oxysporum, F. chlamydosporfum, Penciflfum digitaturn, P. funiculosum and Afternania so, while only 2%. were positive for the presence of aflatoxin B1. Different types of mycotoxins were produced by 50 "/u of grown isolated moulds. These results demonstrate the need of applying quality control techniques in the manufacture of infant foods.
